1 Claim. (01. 43-121) This invention relates to insect traps and has for one of its objects the production of a simple and efiicient insect trap which is so constructed as to deflect odors, shield an unpleasant sight, and provide a space beneath the trap for roaches and other insects to travel to reach the opening the inner container.

Other objects and advantages of the present invention will appear throughout the following specification and claim.

In the drawings:

Figure 1 is a perspective view of the trap showing the exterior thereof;

Figure 2 is a central vertical sectional view of the trap;

Figure 3 is a side elevational view of the inner container showing the corrugations which define the spaced runways;

Figure 4 is a transverse fragmentary sectional view taken on line 4-4 of Figure 3;

Figure 5 is a horizontal fragmentary sectional view taken through the outer covering and inner container and one of the spacing ribs of the inner container covering;

Figure 6 is a horizontal fragmentary sectional view taken on line 6-6 of Figure 2.

Figure 'I is a fragmentary horizontal view in section taken on line 1-1 of Figure 2.

By referring to the drawings, it will be seen that In designates the inner container which is provided with a closed bottom I i and an inclined wall l2 defining a body in the shape of a frustrum of a cone having an opening I 3 at its upper end. A bait I4 is adapted to be mounted within the inner container I13 and preferably rests upon the bottom II in the position shown in Figure 2 of the drawings. This inner container I is provided with corrugations or ribs l which are molded or formed integral with the body of the container and this container [0 is preferably made of glass or other suitable material having a. slick or smooth inner face of the wall l2. The ribs or corrugations l5 may be formed in any suitable or desired shape and may be formed integral with or constructed as a separate part afiixed or secured in any suitable or desired manner to the outer face of the inclined wall l2.

, An outer cover or housing 16 is adapted to fit over and enclose the inner container in and this outer housing or cover [6 is preferably formed of. metal, paper, cardboard, or other suitable material to provide a shield to prevent the contents of the trap from being seen by an observer. This outer cover or housing It is in the shape of a frustrum of a cone, and is arranged to be spaced from the inner container II! for a suitable distance by resting upon the outer faces of the corrugations or ribs l5, as shown in Figure 2, and also shown in Figure 5. The outer cover I6 is also provided with a flat top I! at its upper end which is arranged in spaced relation to the opening [3 of the inner container Ill. The cover or housing I6 is provided with depending tongues 18 formed around its lower edge, which tongues extend in a vertical plane and are arranged in spaced relation to define entrance openings I9 therebetween. These tongues I8 constitute legs for supporting the lower edge of the cover or housing 16, and the lower edges of these tongues or legs l8 are adapted to rest upon a suitable support such as a floor, table or other supporting means A. The entrance openings l9 between the tongues or legs l8 will, therefore, direct roaches or other insects into the trap and these openings is will provide gateways for the entrance of the insects.

I preferably place a traction mat or suitable traction material 20 upon the outer inclined face of the wall I! between the corrugations or ribs l5, which traction material may be of any suitable or desired nature such as felt, fabric, or any roughened material which roaches or other insects may firmly grip to facilitate the climbing of the inclined wall l2 toward the opening B from the entrance openings l9.

It should be noted that the lower ends of the ribs l5 extend vertically relative to the horizontal bottom I I of the inner container In and that the outer cover l6 overhangs the lower ends of the bottom ll of the container In. Because of this structure, a runway is provided which is shielded and unobstructed and extends entirely around the bottom ll of the container. The outer cover extreme care to see that certain parts register in order that the trap may operate. This is especially important where the cover I6 is removable for refilling or cleaning the trap.

, l4. The tractiorrelement 20 prov-ides as footing upon the outer face of the inner container I 0,

-tainer being adapted to contain a bait, ribs and this covering 20 may be of the, same mates v.

rial as the outer cover IE, or of any material.

which would provide a suitable traction.

The top or outer cover or housing. tfifprouldem a deflector of odors for the attraction. of insects. toward the bait, as well as an entrancefor inner container in the shape of a frustrum of a cone having a restricted opening in the top thereof and a closed horizontal bottom, the conformed upon the outer face of the inner container and extending from the bottom to the opening formed in the top of the container, each rib having a vertical wall at its lower ends extending substantially at right angles to said? horizontal bottom-,a removable cover enclosing the container resting" upon said ribs and having a top overlying and spaced from the opening formed in the top of the container, the space between the ribs constituting upwardly inolined runways leading from the bottom of the eomiairiento the top opening thereof, the cover having anopenh lower end extending beyond the "vertical walls of the ribs thereby providing an insects and an apparent habitat.
